“Meghan appeared shy, surprised and stunned at the doting response from their fans. She performed classic self-effacing gestures by hunching her shoulders into her scarf, fiddling with her hair, and placing her left arm across her body.”

“It’s the adult version of a child clutching favourite toy, mother’s skirt or father’s hand when feeling anxious and not knowing what to do or say."
